Cov tshuaj zoo synthesis, PCB etching cov txheej txheem thiab cov khoom siv khib nyiab pov tseg tsis zoo feem ntau xav tau cov khoom siv cua sov kom khiav tsis tu ncua hauv cov kuab tshuaj sib xyaw uas muaj cov kua qaub, muaj zog alkali thiab cov organic corrosive ib txhij. Cov raj cua kub ib txwm ua los ntawm 316 stainless hlau, titanium thiab quartz tag nrho qhia pom qhov tsis xws luag thaum ntsib nrog ntau yam -cov khoom siv corrosive media. PFA heaters txais ib qho tseem ceeb perfluoroalkoxy resin ua cov txheej tiv thaiv sab nraud kom cais tawm cov cua sov sab hauv los ntawm cov kua corrosive. Txawm hais tias cov khoom no tau muab faib ua qib siab- kawg tiv thaiv- cov khoom siv cua sov, ntau lub Hoobkas engineers thiab cov neeg ua haujlwm yuav khoom tseem nug txog nws qhov ntev - lub sijhawm ua haujlwm ruaj khov, qhov tsis zoo thiab qhov rov qab los ntawm kev yuav khoom. Ua ke nrog cov tshuaj inertness ntawm PFA cov ntaub ntawv, ntawm - qhov chaw thov tawm tswv yim thiab hla- qhov sib piv tsis sib xws, daim ntawv no txheeb xyuas cov ntsiab lus tseem ceeb thiab txwv tsis pub siv cov kev txwv ntawm PFA los tiv thaiv - cov cua sov.
PFA nta cov qauv molecular ruaj khov thiab muaj tshuaj lom neeg tsis zoo. Nyob rau hauv nws qhov ntsuas qhov ntev -lub sij hawm ua hauj lwm kub ntau yam, nws NW nyuam qhuav tshwm sim nrog feem ntau inorganic acids, muaj zog alkalis, halide daws thiab cov pa organic reagents. Titanium cua sov raj ua tau zoo heev tiv thaiv ib leeg acid thiab chloride corrosion, tsis tau lawv cov zaj duab xis passivation nto yuav decomposed sai heev nyob rau hauv kub concentrated alkali; quartz cua sov raj tsuas yog tiv taus cov kua qaub yaig thiab yuav maj mam etched thiab puas thaum raug alkaline tshuaj. Tsuas yog lub seamless integrated cladding qauv ntawm PFA tuaj yeem thaiv kev sib xyaw corrosive media. Tsis tas li ntawd, lub ultra- du sab nrauv ntawm PFA tsis tshua tso cai rau cov sediments thiab cov tshuaj residues kom ua raws li kev ruaj ntseg, tshem tawm cov cheeb tsam uas muaj zog corrosion tshwm sim los ntawm cov av tsub zuj zuj thiab txo qhov zaus ntawm phau ntawv tu thiab tu cov kab ntau lawm.
Cov lus hauv qab no sib piv cov ntsuas kev ua tau zoo ntawm plaub lub hauv paus tiv thaiv- cov khoom siv cua sov:
表格
| Hom khoom siv cua sov | Composite Acid-Alkali Corrosion Resistance | Max ua haujlwm kub tsis tu ncua | Anti-Khoom Kev Ua Haujlwm | Risk of Medium Contamination | Tag nrho -Tus Nqi Ua Haujlwm Lub Neej |
|---|---|---|---|---|---|
| PFA rhaub | Sab saum toj -tier comprehensive anti-corrosion peev | 250 degree | Ib txwm; txheej peels tawm nyob rau hauv kev sib txhuam ntse | Zero impurity dissolution | Nruab nrab-siab |
| 316 Stainless hlau cua sov Tube | Tsis zoo, nquag perforation ceev | 560 degree | Zoo heev structural rigidity | Taug qab hlau ion nag lossis daus | Tsawg |
| Ntshiab Titanium Heating Tube | Muaj zog acid tsis kam, yooj yim rau kub alkali | 780 degree | High mechanical toughness | Negligible impurity to | Siab |
| Siab -Purity Quartz Tube | Acid- pov thawj nkaus xwb, hnyav corroded los ntawm alkali | 1180 degree | Tsis tshua muaj zog tiv thaiv kev cuam tshuam | Tsis muaj kab mob | Nruab nrab |
Nws yog pov thawj los ntawm lub rooj hais tias PFA cov cua sov muaj qhov zoo tsis tuaj yeem hloov tau hauv ntau - cov khoom sib xyaw ua ke corrosive ib puag ncig. Hauv PCB etching Rhiav, qhov nruab nrab cua sov yog sib xyaw ntawm hydrofluoric acid thiab alkaline stripping agents. Stainless hlau raj yuav corrode thiab ua rau hluav taws xob xau nyob rau hauv ib lub hlis, titanium raj raug kev txom nyem maj mam yaig los ntawm alkaline Cheebtsam, thiab quartz hlab yog nquag mus tawg nyob rau hauv cov kua. Hauv qhov sib piv, PFA cov cua sov tuaj yeem ua haujlwm tsis tu ncua rau ntau tshaj 20 lub hlis nrog kev ua haujlwm tsis zoo, txo qis kev lag luam los ntawm kev hloov khoom siv ntau zaus thiab lub sijhawm ua haujlwm. Tsis tas li ntawd, PFA nws tus kheej muaj cov khoom pov thawj txhim khu kev qha; txawm tias me me ntawm cov txheej tiv thaiv sab nrauv tuaj yeem tiv thaiv hluav taws xob sib tsoo thiab txhim kho tag nrho cov kev nyab xeeb ntawm cov chaw ua haujlwm tshuaj.
Txawm li cas los xij, PFA cov cua sov tsis tuaj yeem hloov mus rau txhua qhov kev xav tau cua sov. Nws qhov siab tshaj plaws ua haujlwm kub tsis tuaj yeem siab tshaj 250 degree, yog li nws tsis muaj feem xyuam rau qhov siab -kub qhuav cua sov txheej txheem saum toj no. Thaum cov txheej txheej fluoropolymer txheej yog khawb los ntawm cov khoom ntse ntse, lub hauv paus hlau cua sov yuav ncaj qha hu rau cov kua corrosive thiab ua tsis tiav hauv lub sijhawm luv. Tsis tas li ntawd, qhov nyuaj ntawm cov ntaub qhwv thiab cov khoom siv sib khi sib khi ua rau cov nqi tsim khoom, ua rau nws tsis yooj yim rau siv PFA cov cua sov rau cov dej huv huv thiab qis -cov xwm txheej ua haujlwm.
Hauv kev xaus, PFA cov cua sov yog qhov tsim nyog tshaj plaws cua sov kev xaiv rau cov kab ntau lawm plagued los ntawm composite acid thiab alkali corrosion. Txwv tsis pub los ntawm nws cov qab nthab kub thiab tsis muaj zog khawb, nws tsis tuaj yeem hloov pauv lwm yam peb hom cua sov. Cov tuam txhab lag luam yuav tsum ua qhov tseem ceeb ntawm PFA cov cua sov thaum tuav ntau - cov ntsiab lus corrosive cov ntsiab lus, thaum xaiv titanium, quartz lossis 316 stainless hlau cua sov raj raws li qhov kub thiab txias, cov neeg kho tshuab tej yam kev mob thiab pob nyiaj siv rau lwm yam kev sib txuas.
